No, don't make that assumption! NTFS is only POSIX compliant when all access
are through the POSIX layer, which nothing uses (except M$loth's tests to prove
POSIX compliance). None of the Win32 standard libraries pay any attention to POSIX.

Local NTFS works fine for BDB, however, but using the native locking supplied by
the standard Win32 system libraries.

The filesystem is not the issue here; the files are. As long as the BerkeleyDB
files are only accessed by a local process, you are safe. You cannot use a
network map to access the BDB files safely. All other accesses to the
filesystem, whether via a map or local, are unimportant for BDB purposes.
